Buying a house is one of life's biggest decisions—and in Singapore, it's often the largest investment most people will ever make. Whether you're a first-time buyer eyeing an HDB flat or considering a private property, the difference between a wise purchase and a costly mistake often comes down to planning and preparation. Here are five critical considerations that should guide your house-hunting journey.
Financial readiness goes far beyond having a down payment. Many assume they're "ready" with S$50,000–S$100,000 saved, but affordability requires testing three factors: debt servicing ratio (DSR), savings buffer, and income stability.
Singapore's banks cap your Total Debt Servicing Ratio (TDSR) at 55% of gross monthly income for all loans combined—meaning your total monthly debt obligations cannot exceed 55% of your gross pay. For HDB buyers, the Mortgage Servicing Ratio (MSR) further limits housing debt to 30% of income.
Here's the critical detail many buyers miss: banks calculate TDSR using a stress test rate of at least 4%, not your actual loan rate. Even if you're getting a 1.5% package, the bank will assess your affordability at 4% to ensure you can still service the loan if rates rise. MAS requires banks to stress-test at 200 basis points (2 percentage points) above the contracted rate or 4% minimum, whichever is higher.
Beyond DSR, maintain a 6-month emergency fund. Homeownership brings unexpected costs: leaking pipes, broken air conditioners, and property tax adjustments. A home isn't liquid—you can't quickly access equity if you face job loss or a medical crisis.
Example: Affordability Check
For a S$500,000 HDB flat:
Actual loan rate: 2.6% (HDB concessionary rate)
Stress test rate: 4% minimum
Monthly payment at 4% stress rate: ~S$2,640 (25-year loan)
Existing debts: S$800 (car loan)
Total monthly debt obligations: S$3,440
Minimum household income needed (55% TDSR): S$6,255/month
If your household earns S$6,000/month, you would not qualify under TDSR because S$3,440 ÷ S$6,000 = 57%, which exceeds the 55% limit. You'd need to earn at least S$6,255/month to pass the stress test.
Each property type in Singapore comes with trade-offs in cost, timeline, eligibility, and flexibility.
HDB BTO (Build-To-Order)
Lowest cost (S$300,000–S$450,000 for 4-room flats), brand new units with full 99-year lease, eligible for up to S$80,000 in CPF housing grants for first-timers. However, expect 3–5 year waiting periods from ballot to key collection.
HDB Resale
Immediate move-in, wider choice of locations including mature estates, eligible for CPF grants up to S$50,000 for families. Prices range from S$400,000–S$600,000+ depending on location and age, with potential lease decay issues in older flats.
Private Property (Condo/Landed)
Freehold or longer lease options, more facilities (pools, gyms, security), no income ceiling, higher potential capital appreciation. Entry costs start at S$800,000–S$2 million+, with Additional Buyer's Stamp Duty (ABSD) for second properties.
For first-time buyers, HDB flats remain the most affordable entry point, especially with government grants. Private properties suit higher-income households or investors willing to absorb ABSD and higher holding costs.
The sticker price is only part of the equation. Buyers must budget for multiple upfront costs that can add S$50,000–S$150,000+ to the purchase.
Typical Cost Breakdown for a S$500,000 HDB Resale Flat:
Down payment (25% cash/CPF): S$125,000 (minimum 5% cash = S$25,000)
Buyer's Stamp Duty (BSD): ~S$12,600
Legal fees: S$1,500–S$2,500
Valuation/inspection: S$300–S$600
Renovation: S$20,000–S$40,000
Insurance & property tax: S$700–S$1,400
Total upfront: S$160,000–S$182,000
For private properties, add ABSD if buying a second property. 2026 ABSD rates are:
Singapore Citizens: 0% (1st property), 17% (2nd property), 25% (3rd+)
Singapore PRs: 5% (1st), 25% (2nd), 30% (3rd+)
Foreigners: 60% (1st), 65% (2nd+)
A Singapore citizen buying a S$1.5 million condo as their second property incurs S$255,000 in ABSD (17% of S$1.5M), plus ~S$55,600 in BSD—totaling S$310,600 in stamp duties before down payment and other costs.
Many first-time buyers underestimate these costs and find themselves cash-strapped after closing, with no buffer for emergencies or furniture.
Your mortgage interest rate determines how much you'll pay over the life of the loan. In January 2026, rates are near historic lows.
Current Rate Landscape (Mid-January 2026):
HDB Concessionary Loan: Fixed at 2.60% p.a. (CPF OA rate + 0.1%)
Bank fixed-rate packages: 1.35%–1.80% p.a. for the first 2–3 years
SORA floating packages: Around 1.50%–1.70% all-in (3M SORA + 0.25–0.40% spread)
3-month SORA: Currently around 1.0–1.2%, the lowest since August 2022
UOB strategist Peter Chia forecasts SORA will bottom around 1% in Q2 2026 before rising gradually to approximately 1.39% by year-end. For buyers closing purchases in Q1–Q2 2026, this creates a narrow window to lock in near-historic rates.
Impact Example: S$500,000 Loan Over 25 Years
At 2.60% (HDB rate): Monthly payment ~S$2,260, total interest ~S$178,000
At 1.50% (bank floating): Monthly payment ~S$2,000, total interest ~S$100,000
Savings: S$260/month or S$78,000 over 25 years
A 1% rate difference translates to S$300–S$500+ in monthly savings depending on loan size. Buyers who value certainty should consider 2–3 year fixed packages at 1.35%–1.80%, while those comfortable with rate fluctuations may benefit from SORA floating loans.
Not every buyer qualifies for every property type. Singapore's housing framework imposes strict eligibility rules, especially for HDB flats.
HDB Eligibility Criteria (2026):
Income ceiling for BTO flats: S$14,000/month combined household income (S$21,000 for multi-generational families)
Income ceiling for resale flats: S$14,000/month (S$21,000 for extended families); singles face a S$7,000/month ceiling
Citizenship: At least one applicant must be a Singapore Citizen; PRs can apply with a Citizen spouse or family member
Age: At least 21 years old
Family nucleus: Must form a valid family unit (married couple, fiancé/fiancée, parent-child, siblings if orphaned)
Ownership restriction: Cannot own or dispose of private property within 30 months before/after HDB purchase
Buyers who exceed the income ceiling or own private property are only eligible for private resale condos or landed homes. Foreigners face the highest barriers: 60% ABSD on all residential purchases and restrictions on landed property ownership.
Before house-hunting, verify your eligibility on the HDB website or consult a mortgage advisor to avoid wasting time on properties you cannot legally purchase.
Buying a house in Singapore requires thorough planning across five critical dimensions: financial readiness (TDSR stress test at 4%+, MSR limits, emergency buffer), property type selection (HDB BTO vs resale vs private), total upfront costs (down payment, BSD, ABSD at 17% for citizens' second properties, legal fees, renovation), interest rate strategy (fixed vs floating, locking in near-historic lows), and eligibility rules (income ceilings, citizenship, ownership restrictions).
With SORA rates projected to bottom in Q2 2026 before climbing gradually, first-time buyers closing purchases in the next few months have a unique opportunity to lock in mortgage rates at 1.35%–1.70%—levels not seen since 2022. Whether you're buying an HDB flat or a private condo, understanding these five pillars—especially the 4% TDSR stress test and updated ABSD rates—will help you make a confident, informed decision that fits your financial situation and long-term goals.
